Pedreira da Lomba dos Pianos, Casal dos Pianos, Magoito, São João das Lampas, Sintra, Distrito de Lisboa, Portugal


Abandoned basalt quarry included in the Volcanic Complex of Lisbon (VCL).
This volcanic outcrop consists of basalt/dolerite arranged in layers concordant with the sedimentary strata of limestone and marl overlying the Upper Cretaceous. This vein accompanying the sedimentary layers is about 3 km long and can go up to 20 meters thick.
VCL can be observed between Lisbon and Mafra, about 40 km to the north, showing basaltic sheets, tufs, pyroclasts and volcanic breccias, etc. accompanied by a dense net of eruptive dykes.

DGEG: abandoned basalt quarry number 4047 "Casal dos Pianos" (NUT II: Lisboa e Vale do Tejo).



No lugar da antiga pedreira de Lomba dos Pianos, encontra-se um filão-camada, com composição intermédia entre as do traquito e as do basalto, que se intruiu entre os calcários do Cretácico, pelo que estes, devido ao contacto, sofreram metamorfização. O filão possui uma espessura máxima de 20 m e estende-se por cerca de 3 Km ao longo da costa. Aqui é possível ver fenómenos de disjunção colunar e esferoidal, i.e. separação do filão em colunas e em bolas... ref: natural.pt/portal.


AVISO: A área desta antiga pedreira encontra-se em propriedade privada e totalmente fechada no seu perímetro. As visitas são expressamente proibidas e carecem de prévia autorização dos seus proprietários.

WARNING: This quarry is on private property. Access to the mining area is not permitted without prior authorization from the owners.
